Description
Sample kit Spectra/Por® 2 regenerated cellulose is a dialysis membrane kit with a molecular weight cut-off (MWCO) of 12 000–14 000 and a flat width of 45 mm. Regenerated cellulose tubing is widely applied for buffer exchange, desalting and size-selective separation of macromolecules in aqueous biochemical workflows. The sample-kit format lets laboratories trial Spectra/Por® 2 performance before ordering larger membrane quantities. Supplied as one piece with a weight of 0,080 kg, it suits method development in protein work, nucleic-acid handling and other dialysis-based purification steps. This kit from manufacturer REPLIGEN fits filtration, water-purification and separation suites where reproducible MWCO behaviour is essential. The 45 mm width accommodates moderate sample volumes, while the 12 000–14 000 cut-off retains larger biomolecules and allows smaller solutes to diffuse. Ideal for research groups establishing dialysis protocols, comparing membrane grades or validating buffer-exchange conditions under controlled laboratory practice.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Sample kit Spectra/Por® 2,reg. cellulose, MWCO 12000 - 14000, width 45 mm
What is this article?
Sample kit Spectra/Por® 2,reg. cellulose, MWCO 12000 - 14000, width 45 mm is the article on this page. Luminix Health distributes REPLIGEN for laboratory use. It sits in Ultrafiltration & concentrators, inside Filtration, in Lab consumables.
An ultrafiltration device holds back macromolecules above a stated molecular-weight cutoff and passes salts and water. It concentrates a protein or exchanges its buffer. The cutoff, the volume and whether it is a centrifugal device or a stirred cell are the specification. A 0.2 µm syringe filter does not do this.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
